To achieve maximum efficiency, all components of the working process: the band saw machine, the workpiece, the coolant (coolant), the saw blade must function simultaneously.
To obtain maximum efficiency, all components of the working process: the band saw machine, the workpiece, the coolant (coolant), the saw blade must function simultaneously.
The band saw machine is used for cutting profiles and pipes in huge quantities.
Three stages of intermittent sawing: Solid material is being cut.
A thin wall is being cut.
Solid material is being cut again.
The parameters of the workpiece determine the type of band saw and band saw, the type of coolant.
The type of band saw Profile blanks and pipes, including a channel, a beam, do not have a significant mass, which is why they vibrate during the cutting process.
To minimize vibration and whistling, specialized saws with variable tooth pitch are used.
The TPI tooth pitch is digital and sets the number of teeth in one inch.
A saw with a constant pitch of "4" has 4 teeth per inch.
The non-constant pitch of the teeth determines the maximum and minimum pitch on the saw.
Saw 4/6 – has 4-6 teeth per inch.
The variable pitch saw minimizes the harmonic vibrations and screeching that occur during the use of a constant pitch saw.
The minimum number of teeth of a band saw depends on the wall thickness and the width of the pipe.
If 1-2 teeth come into contact with the walls after cutting through the solid upper part, the pressure on them becomes excessive.
Teeth break and become blunt prematurely.
